I sort of use(d) Phoenix. It is/was the closet to the Semagic Windows client. 1.9.6 is the latest official release, but tehre's a 1.10.0 unofficial release that's widely used

btw: with the exception of Phoenix, the clients largely sucked balls. And given more people migrating away from LJ to FB, Twitter, etc there doesn't seem to be much interest in updating any of the LJ clients

I'm not surprised - I tend to use LJ to leave myself lists of reminders etc.
